Milling Machine Features

It is a machine which is used to remove metals from the work piece with the help of a revolving cutter called milling cutter. It is used to machined the flat, rough and irregular surfaces and this is done by feeding the work piece against a rotating milling cutter.
Basically the milling machines are divided into two types first is horizontal milling machine and second one is vertical milling machine. They are further classified as knee-type, ram-type, manufacturing or bed type and planer-type milling machine.

  • Solid cast iron construction throughout.
  • Spindle stop with micro-adjustable setting.
  • Chrome plated precision ground quill. 
  • Table locks for high rigidity.
  • Heavy-duty saddle supports full width of table.
  • High precision ground vertical and cross ways.
  • Class 7 spindle bearings.
  • Lower noise and convenient operation.
  • Dovetail ways X,Y & Z.
  • Adjustable gibs on table.
  • Fine down feed on quill.
  • Head tilts to 90° both ways. 360° rotation on horizontal surface.
  • Adjustable table stops for accurate stops for cuts and repeatability.
  • Variable speed frequency drive allows speeds from 200 to 2250 RPM.
  • Forward/Reversing switch with emergency stop.
  • Fold up safety handles.
  • Adjustable travel stops on X, Y & Z.
  • Scrapping technology X,Y & Z.   
  • Turret-style column.
  • Head slides in and out, swivels, and tilts left-to-right, enabling extremely versatile operations.
